What causes E/Z isomerism?
Restricted rotation around the C=C double bond.
4 of 11
What is an E isomer?
When the functional groups are on the opposite sides.
5 of 11
What is a Z isomer?
When the functional groups are on the same side.

Define the term 'Stereoisomers'
Isomers that have the same structural formula but a different arrangement in space.
7 of 11
What is additional polymerisation?
When the double bond in alkenes open up and join together to make long chains called polymers.

What are co-polymers?
Polymers made up from more than one type of monomer that are joined up in a random order.
9 of 11
What are thermoplastic polymers?
Polymers that don't have cross-linking between chains, they are only held together by weak intermolecular forces. This means the plastic is easy to melt as the forces are easily overcome.
10 of 11
What are thermosetting polymers?
Polymers that are held together by cross-linking chains in a 3D giants covalent structure. They don't soften when heated, and they are strong, hard, rigid and insoluble.
